On April 11, 2012, puCK and Fitzyhere competed against each other in a BO21 showmatch to find out which of them would become part of ROOT Gaming's roster. After a hard fought battle puCK emerged victorious with a 11-8 score and joined ROOT's roster. As it happens ROOT accepted both Fitzyhere and puCK to their roster. On October 16, 2012, ROOT Gaming announced that puCK would be leaving the team to focus on personal issues.[1] A month later, puCK re-joined the team.[2]

In WCS America 2013 Season 1, puCK was one of two players, alongside DeMusliM, to qualify for Premier League through the Challenger League qualifier and bracket stages. This included a 2-0 victory over Suppy, the best performing American in Season 1.

puCK played in the Acer TeamStory Cup Season 1 starting on March 27, 2013, as a member of ROOT Gaming. puCK was fairly successful in PvT and PvZ, going 3-0 and 3-1, respectively, but had an abysmal 0-6 record against Protoss for a subpar total score of 6-7.

In the final season of the 2013 WCS America, puCK was placed in a group with teammate Minigun, CranK, and Scarlett. After falling to Scarlett 1-2, puCK defeated Minigun 2-1 to face CranK in the final match. In the third game of the match, puCK fell victim to an unusual Stargate into Dark Templar build to fall out of the tournament in the Round of 32. In Challenger League, puCK defeated JonSnow 2-1, received a walkover past Revival, and defeated HuK 2-1.

On October 17, 2013th, puCK announced his departure from ROOT Gaming.[3]

As of October 25, 2013, puCK is listed as a part of the Clan Team2Pro.[4]

Based on his performance in the previous WCS season, puCK received a spot in the WCS America 2014 Season 1 Challenger League matches. On January 22, 2014, he defeated the Taiwanese player Ian 3-1 to qualify for Premier League. On March 12, 2014, played his Premier League group with SeleCT, MacSed, and Sen. He won against SeleCT 2-0 using Oracle openers effectively both games. He then lost 1-2 to MacSed after playing two drawn out games against the Chinese Protoss player. In his final match, puCK defeated Sen 2-0, including a game where he killed over 160 of his opponents Roaches. With a 2-1 match score in the group, puCK advanced to the live Round of 16 portion of WCS America which, due to the end of NASL's StarCraft II involvement, took place in Cologne, Germany.

puCK's WCS America 2014 Season 1 Premier League Round of 16 match took place on April 5, 2014. After losing the first game of his match against HyuN, he came back to win the match 2-1. He faced Oz in the winner's match and narrowly lost 1-2 to fall to the final match, where he again faced HyuN. Unable to win a second time, he lost 0-2 to drop out of the season.

puCK qualified for the 2014 Red Bull Battle Grounds: North America on June 16 after winning the first qualifier and defeating viOLet in the finals of that qualifier. The tournament format was unusual in that each player in turn was allowed to challenge one of the remaining competitors and remained in the tournament until they had lost three matches. puCK began the tournament selecting viOLet as his opponent, but ended up losing the match 0-2. He was then challenged in each of the next five matches, where he defeated Scarlett, viOLet, and MajOr, and lost to HuK and Polt. He was therefore eliminated on the first day, and thus despite a 3-3 record, which was tied for second best at the event, received no prize money.

The following weekend on June 20, puCK competed at the 2014 MLG Anaheim tournament, where he was seeded into the pools after qualifying in the second online open qualifier. He had a 2-5 match score in the pool, including a victory over Incredible Miracle's Trap, and was subsequently eliminated in the Loser's Bracket 0-2 by KeeN.
